Tesamorelin
Tesamorelin – 10mg (Lyophilized Peptide) – For Research Use Only
Tesamorelin is a synthetic peptide analog of Growth Hormone-Releasing Hormone (GHRH), studied for its potential to stimulate endogenous growth hormone secretion in controlled research environments. Research models have explored its role in lipid metabolism, adipose tissue regulation, and metabolic pathway function. Its GHRH analog structure makes it a subject of interest in studies on the GH axis and endocrine signaling mechanisms.
